Fig. QOis a corresponding end view of these parts.

Figs. 21 and 22 are respectively enlarged fragmentary plan and side views of the brush-reciprocating mechanism and control.

Referring now to the drawings in which the various parts are indicated by numerals, 1 indicates the frame of the machine. 2 are cross rails extending from one side of the frame to the other on which rails the toe-I shining, and polishing, mechanism is shifted to transfer from one shoe to the other. 3-3

are similar rails on which the heel-polishing mechanism is shifted transversely for the same purpose. H are side members of the carrier for the toe-shining, and polishing, mechanism. 5 are bottom members and 6 top members joining the side members 4 at their upper and lower ends respectively. 7 are rollers which are journalled in the side members 4 and which rest on the upper surface of the transverse members 2. 8 are rollers correspondingly journalled, which bear on the under side of the same members these sets of rollers providing means permitting shifting of the carrier.

The carrier for the toe polishing mecha' nism will hereinafter be designated as the belt-carrier, and the mechanism as the belt mechanism. The carrier for the heel polish! ing mechanism comprises longitudinal members 9, lower and upper transverse members 10, 11, and vertical side members 12. In these vertical side members 12, rollers 18, 14 are mounted, which rollers respectively rest on the upper surface of the transverse members 3, and bear against the lower surface thereof, to provide means permitting lateral shifting of the heel polishing mechanism. The carrier for the heel polishing mechanism will hereinafter he designated as the brush-carrier, and the mechanism, as the lJILlSll-HIGClltL- nism.

From the lower member-5 of the belt-carrier an arm 15 extends downwardly and is provided at its lower end with a pin :16. Similarly, an arm 17 extends downwardly from the bottom member 18 of the brush-carrier. This arm 17 is also provided with a pivot pin 19, which en gageswith a slot 20 in one end of an arm 21, the pin 16 engaging the slot 22 in the opposite end of the same arm.

The arm 21 is pivoted on pin23, carried by pedestal 24lextending upward from the base of the main fral'ne, so that when the beltcar-rier is shifted to one side, the brush-carrier will be shifted to the opposite side. The shifting mechanism accomplishing this will be later described.

8/106 supports.

Extending upward from the base 25, are

standards 26, 26*, which carry a frame comprising arms 27, 27 and a cross member 27 the arms 27, 27 A being longitudinally slidable in the hubs 26 and 26 at the upper ends of the standards 26, 2,6 The arms 27, 27 carry hubs 28, 28 in which is mounted a vertically slidable frame comprising posts 29, 29 and an integral cross member 29". 30 are springs normally forcing the arms 27, 27 A backward. Similarly the posts 29, 29 are normally held in raised position by springs 31. vThe upper end of each post carries a shoe rest32. By these various members the shoe rests 32, may be adj usted both vertically and longitudinally with reference to the polishing mechanisms. It will be noted that because of the unitary construction downward movement of one foot rest causes corresponding downward movement of the other and similarly any forward movement is in unison. 38 is an indicating arm which determines the proper location of the toe of the shoe, so that the shoe to be shined, may be adjusted to the proper position. 34 is a seat. The adjustment is accomplished by placing the foot on the rest an d pushing downward and forward until the upper edge of the right shoe comes against the indicator arm When the shoe rests have been brought to position, the indicating arm is turned outward about the center 33 causing the rod 33 projecting rearwardly past the bracket 28 to engage the lower end of the latch 33 and force same outward thus engaging the upper end of the latch with one one Toe-polishing moo/mutant.

The belt-smechanism for polishing the toe of the shoe comprises a belt made up of a cleaning-belt 35and a polishing-belt 36, which are joined .at the central point, A, into a single belt, the ends of whic are fastened to the half-drum 37. The drum .37 is mounted on and secured to a shaft 38, as by aset screw 39. The shaft 38 isioscillatably mounted in bearings i0, and carries on the end opposite the drum 37, a swingingarm al, which is secured to the shaft, as bya set screw 42. The lower end of the arm 4-1 carries a yoke 43, which is oscillated by a crank pin 14. 4;54c6 are crank pin arms which are respectively .provided with, a journal 47 which rotates in the bearing d8, and a journal pin 49 which rotates in a bearing 50. These bearings are carried on the upper end of .a yoke arm 51, which yoke aia'i'iswings about a pin'52, secured in the lower end ofa post 53, which post is integral with the belt-carrier frame.

The pin 4-9 ournals a belt-wheel 54, which beltovheel is driven by a smaller belt-wheel 55, through a belt 56. The belt-wheel has two belt grooves, and is journalled on the pin 52. '57 is a drive pulley mounted-on and secured to the main driving shaft 58. 59 is a belt from thedri-re pulley 57 :to the second groove on thebelt-wheel 55. =6061 are fixed stops projecting from the frame member 5 which limit the swinging motionof the yoke arm 51. 62 is a locking member, :retaract'a'bly mounted in the post 53 and adapted to engage lugs 636- l, projecting from the yoke arm 51 and thereb-yhold the yoke arm in either of two positions.

At the upper end of the swinging or yoke arm 41, are pins6566 spaced equal'distances above and below the shaft 38, on which pins ratchet arms 67-68 respectively are mounted, these being more clearly shown in Figs. 6 to 9 inclusive. 69 is a tension spring connecting these arms, and 70, 71 are pins carried by an extension 7 2 from the upper beltcarrier member 6, and by the member 6 respectively, which pins limit motion of these arms toward each other. 73 is a trip arm, pivotally carried by a bolt 7 4, on an extension 75 from the member 6. 76 is a tension spring, having one end secured to a pin 77, carried by an arm 78 extending from the member 75, and the other end engaging a pin'79, projecting from the trip arm 7 3. 80 is a trip yoke armor yoke, which embraces the :trip arm 73 and is mounted on and secured to a shaft 81, which is journalled in and is slidably mov able transversely to the upper end of a tube 82, which tube is secured to the frame member 6 and to a member 83 projecting laterally from the post- 53. 84, 85 are arms of a bell crank lever also mounted on the shaft 81 adjacent the yoke arm 80. 86 is a pin, projecting from an extension 87 of the trip yoke 80 into the path of the arms 84, 85 of the bell crank lever, between which arms it is positioned. Extending laterally from the bell crank lever is a dog which has ears 89, 90. 91 is a shift arm, having yoke at its upper end embracing the shaft 81, and lying between the bell crank lever arms 84, 85 and the tube 82. This arm is pivoted at 92 and has on the lower end thereof a roller 93 adapted, during certain movements of the yoke arm 51, to engage with, and be displaced by, a cam 96 integral with the bearing 48. 97 is a fiat spring, having a forked end embracing the pin 81 and normally holding the pinand the bell crank lever arm 84, 85 carried thereby, toward the tube 82, and holding the ears 89, 90 positioned in line with trip lugs 98, 99 on the upper end of a trip rod 100, which rod is slidcbly mounted within the tube 82. 101 is a tension spring normally tending to hold the rod 100 raised. On the lower end of the rod 100 is a wedge-shaped cam 102 which engages a cam member 103 forcing it outward when depressed. 104 is an arm, pivotally attached to the locking member 62, and loosely pivoted to cam member 103. The outer end of the arm 104 has a lug 105 projecting inward and normally resting against, the frame member 83. 106 is a spring tending to hold the arm 104 toward the frame member 83.

108 is a shift-gear which is journalled on the member 6. This gear has teeth which are adapted for engagement by the pawl 67, or in shifted position of the pawls, by the pawl 68. 109 is a pin projecting from the gear 108 into the path of the bell crank arms 84 and 85.

The halves 35, 36 forming the belt, extend downward from the drum 37 and pass over idlers 110, mounted respectively on arms 111, 112, which arms in turn are pivoted at 113,

114 on the frame 4. A spring 115 and a similar spring not visible, normally hold the arms 111, 112 down and the belt taut. A cross arm 116 extends from the arm 112 across to, and beneath the arm 111, so that the arm 111 will be raised when the arm 112 is raised. A continuation 112 of the arm 112, extends beyond the pivot 114 and carries a trip arm 117, which arm is provided at its lower end with a forwardly projecting lug 118.

1.19 is an arm, integral with and extending substantially, at right angles from the lower end of theyoke member51, this arm having a projecting end 119 adapted in one position of the arm 119 to engage the lug 118. 120 is alatch oscillatably mounted on the arm 119 and having a forwardly extending arm 120 disposed in the path of a trip member 123 which is integral with the arm 123, and projects upward therefrom. 121 is a bevelled wheel, which is journalled in a bracket 122, integral with and extending downward from the arm 119. 123 is an arm, pivoted to the frame member 1 and supported by a springprojecting end 119*.

Shifting mechanism.

130 is a horizontally disposed ratchetwheel, rotatably mounted on a bracket 131, extending upward from the base 25. Engaging this ratchet wheel, is a dog 132, which is reciprocated by an eccentric 133 mounted on the main shaft 58. Projecting from the upper side of this ratchet wheel is a pin 134, which engages a slot 135 in the arm 21. Rotation of the main shaft, will therefore advance the ratchet wheel step by step and oscillate the arm 21, shifting the belt-carrier and the brush-carrier. In order to time and interrupt this movement an arm 136, integral with the dog 132 is extended rearwardly and is secured to a spring 137 the opposite end of which in turn is secured to an arm 138, which is integral with and extends downward and rearwardly from the arm 123, so that when the latter is depressed by the wheel 121, the

dog 132 is thrown into engagement with the ratchet Wheel 130 and operates the same until the arm 123 again raises and releases it.

Brush mechanism.

141 are brushes which polish the back, sides, and extreme toe of the shoe. These brushes are each mounted for rotation, on shafts journalled in bearings 142, and driven through gearing 143, by individual motors 144 (indicated only). Each bear-in 142 carried by a bracket arm 145, to which. the motor is also secured. This arm is oscillatably mounted on a pin 146, extending from the members 147. 148 desi .ates a train of gears, such as is ordinarily used on oscilatable-fan motors and well known, which gears act-ing thr igh an arm 149, hinged to the frame hers 147, slowly oscillate the brushes. The frame members 147 extend horizontally from vertical members 150, to which they are pivoted on pins 151, and are yieldably drawn toward each other by a spring 152. 153, 154' are lugs, which extend upward from a forked guide 115, between the members 147 and limit the movement of the members 147 toward each other. Each of the vertical members 150 is carried by the forked guide 155, slidably mounted on a rail 156, the two guides being rigidly connected, and adapted for oint reciprocation on these rails, by means of a lever 157, having a fork 158, engaging a pin 159 extending from one of he members 147. The lever 157 is pivotally mounted on a pin 160 carried by a bracket 160 extending down ward from the nieuiber 9. 161 is a connecting rod, pivoted to the lever 157 by a pin 162, and to the bevel gear 163 by the crank pin 164. The gear 163 is driven by a bevel pinion 165, which is rotated with a step by step motion, by a ratchet pawl 166, which engages with the ratchet wheel 167. The ratchet pawl is reciprocated by an eccentric 168, mounted on the main driving shaft 58. 169 is a shaft, mounted in bearings 170, which carries pawl trips 171172 and a trip arm 173. The end of the trip arm 173 extends into the path of a pin 174, which in turn is carried by a ratchet wheel 175. This ratchet wheel is advanced by a ratchet pawl 176 carried by the arm 1.57, so that when the arm 157 has made apredetermined number of strokes, being one less than. the total number of ratchet teeth, the pawl 166 will be disengaged and reciprocation cease. 177, 178 are spring cams, carried by the cross member 179 which act as detents for the ratchet wheel in its alternate shifted positions. When the brush carriage is shifted, after reciprocation of the brushes has ceased, these cams also act to engage .a tooth of the ratchet wheel 175, and advance same additionally as the shiftis completed to cause the pin 174 to advance past, and release, the arm 173, permitting the pawl 166 to again engage the ratchet wheel 167 and retard the reciprocation of the brushes. The pawl 166 may be normally held in engagement with .tl e wheel by some such means as a tension spring not shown.

Polishing paste and cleaning fluid for brushes.

180 is second pin, carried by the ratchet 175, which engages the end. and 181 of a lever arm which is pivoted on the post 182. To the opposite end 183 of this arm, a cord 184 is connected. The opposite end of the cord 184 is connected to an arm 186, extending laterally from and secured to the lower end of a rod 187, which extends upward and carries a gear 188. The gear 188 meshes with a. similar gear 189 and the two gears carry respectively fiat trays 190, 191, which a re filled with polishing paste. The gears and trays are supported by an arm 192 extending upward from the member 156. 194 is a spring normally acting to keep the trays closed together.

195 is a third. pin on the ratchet wheel 175, which pin engages one end of a lever arm 196 mounted on the post 182. From this arm a cord 197 extends to an arm 198, which is secured on the lowerend of a rod 199. This rod extends upward and .is secured to Ithelower end of .a tube 200 which is rotatablymounted within a cleaning fluid chamber 201. The tube 200 is provided with vertical slots 202, or holes which are normally out of alignment with. perforations 203 in the walls of the outer chamber. hen however the arm 198 is shifted by the cord 197 the holes .andsloltsare brought into alignment providing egress for the t1 uid. 204 is a tube leading from the supply tank 193 to the cleaning fluidchamber.

Gleam rig fluid and polishing pasta? for belts.

Extending upward from the-arm 111 Figs; 12, 13 and 14) is an integral post 23-l-on-which is pivoted a tubular arm 232 adapted to swing in a generally horizontal plane. One end of this tubular arm carries and communicates with theinterior ofa hollow cylindrical cleaning fluid container .233 which is provided with openings 234. 235 is a .flu-id tank and 236 is a tube from the tank to the arm 232 whereby comn'iunication is established, from the tank to the cleaning fluid container 233. Encircling the container 233 is asleeve 237 having openings .238 which do not register circumferentially with the openings 234, but which may be rotated into register therewith. 239 is an arm integral with the sleeve 23.7 which arm extends into proximity with the arm 111. 240 .is :a deflecting arm extending from a frame member 4 zdIlCl having the upper portion 241. thereof bent inward toward the belt 35 to form a deflecting cam. 7

When the arm 111 is swung'upward or returns downward the arm v232 is deflected by this cam into contact with the belt .35. At the same time the sleeve arm 239 striking thearm 111 rotates the sleeve .bringingthe openings 238 into register with the .openings234 and permitting the cleaning fluid to escape into the belt 35.

The post 231 extends above the arm 232 and carries pivotally mounted thereon-a paste-carrier arm 242, an extension 243 of which extends past the frame members-4 and into the path of an arm 244 which (Fig. 2) ,ismounted on a pivot 245 and thence-extends into the path of the pin 109 on the gear 108. This farm 242 carries a paste container 247, which :is rotatably mounted thereon. 248 is an enclosing case, which is carried by an arm 249 extending from the arm 111, within which case the paste container is normally disposed. 250 is acord attached to the lower side of the paste container and the upper side of the case 248. When therefore, the arm'244 is moved by pin 109 on gear 108 shifts the extension 243,. (of the arm 242), away from the frame members 4, the paste container 247 is swung away from the case 248 and being restrained in its movement by the cord 250 is rotated, thus bringing the open side of the container outward and the paste contained therein, into contact with the belt 35. 251 is a spring resisting the rotative movement of the container 247 and cansing the same to rotate into the case 2 18 on its return movement.

Referring now to Fig. 2 and Fig. 11, 205 IS a coin tube, 206 is a coin detent, which is secured to a stop 207, both being pivoted at 206*, and the stop 207 being disposed in the path of a lever 208, which lever is pivoted at 209 to the lower side of the seat 34. 210 is a coin in the tube 205, 211 is a coin box. 212 is an extension of the lever 208 beyond the pivot 209. 213 is a cord, or wire, connecting the extension 212 with one arm of a bell crank lever 214, the other arm of which, is connected through a cord 215 with an arm 216 extending upward from a cross rod 216 which is rotatably mounted in bearings 216 216 is an arm extending downward from the rod 216, and 216 a tension spring from this arm to the post 26.

217 is a trip extending upward from the rod 216 and disposed adjacent to a swinging arm 218 hinged to, and depending from, the arm 220 of a bell crank lever 220. It will especially be noted that while the arm 218 may swing backward, that it has no lateral movement with reference to 220*, and that the said arm 218 is in the lateral path of the pin 134.

Depending from the lever 220 is a latch 219 having a forwardly turned lower end 219 extending beneath the extension 136. Extending upward from the lever 220 and integral therewith, is an arm 220 which engages a pin 221 which projects forwardly from the indicating arm 33.

222 is a contact carried by the lever 220 and insulated therefrom by insulation 222 223 is a similar contact plate carried by a bracket extending from the post 26 and similarly insulated, 22 1 are circuit wires leading to some suitable source of electric current not shown, and to the motors operating the mechanism, such wiring being of usual form and not necessarily shown or further described. 225 indicates the motor which drives the shaft 58, through any suitable or desired reduction gearing such for instance as a worm and gear.

Operation of the machine.

The customer seats himself on seat 3 1 and places his feet on the foot-rests 32. He presses the foot-rests down and forward against the tension of springs 31 and 30, until the upper edge of the right shoe just touches the indicator arm 33. He drops a suitable coin in the tube 205. The coin travels down the tube 205 and comes to rest against the detent- 206 which is fixed to the stop lever 207. The customer presses down on the knob on the lever arm 208, which causes the bottom of the lever arm 208 to hit the top of the coin 210 forcing the stop lever out of the way of the lever arm 208, permitting 208 to move down all the way. The coin is at the same time allowed to fall through the tube 205 into the coin box 211.

As 208 moves down, the other end 212 of the lever moves up carrying the wire 213 with it. This causes the trip 217 to press against the swinging arm 218 deflecting it from the path of the pin 13 1. This allows the spring 137 acting through the latch 219, to pull down the lever 220 and press the dog 132 into engagement with the ratchet Wheel 130.

The end of the lever, 220 presses against the pin 221, causing the indicator arm 33 to rotate about 33 and assume the horizontal position. WVith the indicator arm in this position, the foot-rests are clamped. As the lever 220 comes down the upper contact plate 222 is caused to touch the corresponding plate 223 which closes the circuit of the motors and starts them operating.

As the main shaft rotates, the dog 132 causes the ratchet Wheel 130 to advance, which shifts the belt-carrier and brush-carrier to one end of their travel,in the position shown in Fig. 5. During the process of shifting, the arm 123 is kept in a horizontal position by means of the bevelled wheel 121. At the end of the travel, the wheel 121 rolls off the track 126, its bevelled edge causes the lug 128 to be deflected, allowing the arm 123 to rise. This releases the tension on the spring 137 so that the dog 132 is disengaged from the ratchet wheel 130, and the shifting operation is stopped. The rise of 123 also causes the projection 123 to strike the arm 120 of the latch 120, causing it to oscillate and release the lug 118. bear upon the belt holding it taut against the front of the shoe. As the arm 112 comes down, the cleaning fluid container 23? is forced against the cleaning belt '35, by the cam 241. The sleeve arm 239 is deflected by the arm 112, which causes the fluid to flow out of the openings and onto the cleaning belt 35.

As the travel of the brush-carrier ends, the ratchet wheel 17 5 was advanced by means of the cam spring 17 7 which caused the pin 17 4 to advance past and release the arm 173, permitting the pawl 166 to engage the ratchet wheel 167. The belt carrier is now ready to work 011 the front and top of the left shoe, the brush-carrier is ready to work on the back, sides and toe of the right shoe.

Gleaming and shining front of left shoe.

' At the start, the yoke arm. 51 is in the position shown in Fig. 1. The belt wheel 54: is caused to revolve with the main drive shaft, by means of the two belts 56 and 59 and the belt wheel 55 and 57 and the swinging arm 4:1 is oscillated through an are that lies on toe left of its central position (Fig. 1). This causes the cleaning belt. 35 to move back and forth across the front of the shoe. This rubs the cleaning fluid into the leather and cleans This allows the arms 111 and 112 to the front of the shoe. As the arm 41 oscillates, the gear 108 is caused to rotate step by step in a clockwise direction by the pawl 67. When the gear wheel is advanced a predetermined number 0% steps, the pin 109 deflects the lever 244 which in turndeflects lever 243 opening the polishing pastecontainer and causing polishing paste'to beapplied to the cleaning belt, and from the belt onto the shoe by the continuous to and fro motion of the belt. The gear 108 makes two revolutions during the process, of cleaning the front of the shoe so that the-polishing paste is applied twice. S/iiftiiig from cleaning belt to polishing bell. At the end of the'iirst clockwise revolution of the gear 108, the pin 109 strikes the arm 84 of the bell crank lever and brings the lever around to the position shown in-Fig. G-so that the arm 85 lies in the path of the pin 109. At

the end of the second clockwise revolution of gear 108, the pin 109'strikcs the arm 85. Duringthe last step of the revolution the arm 85 strikes the pin 86' and shifts the yoke-arm to its other position. This causes the trip arm 7 3 toshift to its other position allowing pawl 67 to swing in torest against the pin 70 and carrying pawl 68 out to a position when it is adapted to engage with the gear 108.

As the arm is shifted during this last step, the car 90, being integral with the arm 85, turns with it and pushes down the trip lug 99. This depresses the-cam 102 and forces out the cam member 103. The arm 104 is thus pushed out against the tension of the spring 105 which exerts a pressure tending to push out the locking member 62. This member does not come out immediately because so long as the pawl67 acts on the gear 108 there isa pressure exerted on member 62 by the lug 63, which holds this member in place. But when pawl 67 reaches the end'ot its stroke and starts coming back, the pressure on member 62 is released and this member is pushed out of the path of lug 68. At this point the gear 108 has reached the end of its second clockwise revolution and the arm 41 is in its extreme outer position. It now swings back to its extreme inner or central position and tends to swing back again. But the pawl 67 is now resting against the pin 70 as stated above and hits the gear 108 as arm 41 tends to swing back, which prevents this arm from swinging to the left of its central position. The belt wheel 54 keeps on turning, however, and the locking member 62 being now out of the way, as stated above, the yoke arm 54 is caused to swing to its right or polishing belt position.

The cam 96 strikes the roller collecting the shift 91, which in turn shifts the shaft 81 and the bell crank lever thereon. This causes the ear to slide the trip lug 99 and thus release the latter which causes the locking pin 62 to tend to resume its former position, so that when the yoke arm 51 reaches its extreme right position, the pin 62 springs outward into the path of the lug'64, thuslocking the yoke arm 51 in its position the right of the center line of the belt-carrier frame.

Polishing from of left shoe.

The swinging arm 41 will now oscillate through an are lying on the right oi its central position which causesthe polishing bell 36 to move back and forth across the iront oil the shoe as the wheel rot s. As'the arm 41 oscillates, gear 108 rotated in a counter clockwise direction by the pawl 68. hit the'end of the first revolution e1? gear-108', the pin 109 strikes arm 85 and brings the bell crank lever around so"- that the arm 84' lies in the path of the pin 109. At the end of the second revolution, the pin 109 strikes th'e arm Durii'ig the last step o1"- this revolution, the arm 84 strikes the pin 86 sri ilts' the yoke arm 80 to its first position. This causes the trip arm 73 to shift to its-first position, allowing pawl 68 to swing to'rest against the pin 71 and carrying pawl 67 out to-the positi'on shown in Fig. 6, where it is adapted to Cleaning and polishing back, sides and co;- treme toe of right shoe.

The cleaning. and: polisl-iing of the back, sides and extreme toe of the right shoe is accomplished during the same time that the front 01 the left shoe is be'ingworked on. As the main shaft rotates, the ratchet wheel 1 67 is rotated with a step. by stop motion: by the pawl 166. The bevel pinion. 165,. integral with ratchet 167, turns the gear 163 which causes the rotary brushes to have a rccipro eatery motion with respect to the shoe, the brushes dividing, against the tension oi the spring 152, they strikethe shoe and travel= ing one on each side. The brushes aregi-ven a rotary motion by means of the individual motors 144 and. an oscillatory motion by the train of gear. 148.

As the lever 157 swings, the ratchet wheel 175 is rotated by the pawl 176. Aiter one step the pin 195 engages the end oi'the lever arm 196, which shifts the cord 197 and causes the cleaning fluid to escape from the cham er 202 to be taken up by the'rotary' brushes as they pass and be depos ted on the shoe by these brushes. After a prerermined number of steps (about half the number of teeth on the wheel 175), the pin 180 engages the end 181 of the lever arm 183 pivoted on the post 182, causing the polishing paste trays 190 and 191 to be opened. The brushes then take up some of the paste and apply it to the shoe. 8

When the arm 157 has made a predetermined number of strokes, (one less than the number of teeth on gear 175-), the pin 174 strikes the arm 17 3, rotating the shaft 169 and musing the dog 172 to force the ratchet pawl 166 out of engagement with the ratchet 167, reciprocation of the brushes ceases and the brushes are left in the position shown in Fig. 2 ready to be shifted to the other shoe.

Shifting from one shoe to the other.

When the polishing of the front of the left shoe and the simultaneous cleaning ant polishing of the back and sides of the right shoe just described has been accomplished, the gear 108 will have accomplishedits second counter clockwise revolution as before described under polishing front of left shoe and as there described have tripped arm 73 to shift the pawl 67 into actuating position, and the pawl 68 into engagement with the ends of the teeth on 108 to cause yoke arm 51 to shift about the pin 52 as a center, to its extreme left position. In previously shifting to its right position, shown in Fig. 17, the movement began with the parts as shown in Figs. 15 and 16. In this position the bevelled wheel 121 held the lug 129 displaced, so that the arm 123, urged upwardly by the spring 124 (Fig. 1), brought the trip member 123 against the arm 120 shifted the latch 120 and thereby displaced the trip arm 117 and its lug 118, and at the same time was checked in its upward movement. As then the yoke arm 51 shifted the integral arm 119, carrying the projecting end 119, was raised eventually reaching the position shown in Fig. 17. During this movement the trip member 123 moved upward in engagement with the arm 120 until the extension 119 passed above the lug 118 at which time the stop 125 (Fig. 1) stopped the upward movement of the arm 123 and permitted the lug 118 to swing beneath the extension 119*, and the lug 129 to resume its normal position beneath the wheel 121. When therefore the yoke arm 51 now swings to its left position the roller 121 strikes squarely on the top of the lug 127 and depresses the same so that the latch 123 does not engage the arm 120 and the extension 119 engages the lug 118, thus depressing trip arm 117 and the continuation 112 of the arm 112, and thereby raising the end of arm 112, and through the cross arm 116, the corresponding end of the arm 111.

The belt rollers 110 carried by said arms, are thereby raised above the shoe levels. At the same time the depression of the arm 123, just mentioned, causes the spring 137 to throw the dog 182 into engagement with the ratchet wheel 180, rotating it, and thereby, through the pin 13%, causing the arm 21 to shift the belt-mechanism to the right shoe, and the brush-mechanism to shift to the left shoe, the wheel 130 making a one-half revolution in doing this. When the new position is reached, the roller 121 will engage the beveled edge of the lug 128 and be deflected thereby, allowing arm 123 to rise and trip 123 to strike arm 120 disengaging lug 118 and allowing arm 123 to rise and disengage dog 132. Thereafter the operation cycle described hereinbefore is repeated on the front of the right shoe and the side and rear of left shoe.

On completion of this operation reverse shift is made as above described under shifting, and the wheel 130 caused to complete the revolution. This will bring the pin 13% to its initial position (Fig. 11). As the pin reaches this position it strikes the arm 218 deflecting the same, and raising arm 220 separating contacts222 and 223 and sto iping operation of the motors.
